The airbag module is provided with a cushion 20 to protect the passenger from collision of the vehicle and is deployed toward the passenger.

즉, 차량에 충돌이 발생하면 ACU(Airbag Control Unit)에서 전기적 신호를 보내게 되면 인플레이터가 작동하여 고압의 가스를 분출하게 된다. 상기 가스가 상기 쿠션(20) 내부에 충진되어 상기 쿠션(20)은 전개된다.In other words, when a collision occurs in the vehicle, the ACU (Airbag Control Unit) sends an electrical signal, and the inflator operates to eject high-pressure gas. The gas is filled in the cushion 20 so that the cushion 20 is expanded.

이때, 상기 쿠션(20)의 상측에 폴딩되어 위치한 플랩(40)이 펼쳐지면, 도 3에서와 같이 되고, 상기 쿠션(20)이 만충되면, 즉, 상기 도 3에서보다 많은 가스가 충진되면 커버(30)와 플랩을 연결하도록 봉제된 가접부(55)는 뜯어지게 되어 상기 쿠션(20)은 만개하게 된다.3, when the cushion 20 is fully charged, that is, when more gas is filled in the cushion 20 than in FIG. 3, the flap 40 is folded, The abutment 55 sewn to connect the flap 30 with the cushion 20 is torn and the cushion 20 is full.

상기 커버(30)가 가이드하여 상기 쿠션(20)이 승객을 향하여 만개하게 되어 승객을 보호하게 되므로 상해치를 줄이게 된다.The cover 30 guides the cushion 20 toward the passenger so as to protect the passenger.
